4, SUMMARY OF RESULTS, DISCUSSION AND RECOMMENDATION <br /> A summary of the analytical results from current andast well resented in Table <br /> P sampling P 9 is P <br /> 1. Figure 2 shows the groundwater elevation contours for March 6, 1996, based on the water <br /> level data in Table 1. Since June 22, 1995, the groundwater elevations rose an average of <br /> 3.33 feet, ranging from 3.28 feet in Monitoring Well MW-2 to 3.36 feet in;,Monitoring Wells <br /> I <br /> MW-1 and MW-3. The apparent groundwater flow direction for March 6, 1996, was <br /> southeasterly at.a gradient of approximately 0.002. No TPH-D, TPH-G, BTEX or MTBE were <br />{ detected in groundwater samples collected from Monitoring Wells MW-1, MW-2 and MW-3 <br /> during this round of sampling. Figure 3 shows the concentrations of TPH-D, TPH-G, and <br /> benzene detected in the groundwater on March 6, 1996. <br /> 1. <br /> As can be seen in Table 1, laboratory results indicate that no TPH-D, TPH-G or BTEX has <br /> i 4. II <br /> ever been detected in Monitoring Well MW-1 since monitoring was initiated in July of 1990. In <br /> Monitoring Well MW-2, TPH-D has not been detected 'ssince monitoring was initiated in August <br /> 1990 and TPH-G and BTEX have not been detected"since March 1991. In Monitoring Well <br /> MW-3, TPH-D, TPH-G and BTEX were not detected from March 1991 through June 1994, in <br /> June 1995 a very low concentration of TPH-D (72 ppb) was detected in Monitoring Well MW-3 <br /> (TPH-G and BTEX were not detected). A confirmation of this anomalous detection was <br /> performed in August 1995, in the confirmation analysis TPH-D was not detected. In March <br /> 1996, TPH-D, TPH-G, BTEX and MTBE were not detected in any of the monitoring wells. In <br /> consideration of the above results, we recommend that this site be considered for closure. <br /> l .. <br /> I <br /> F <br /> MVIW:\94-2611QUIK-120.RPT[23-Apr-861 SWFH <br /> I <br /> I <br />
